Thank you for taking the time to file an issue!

This tracker is for issues related to:

I followed the instructions on https://dart.dev/tutorials/web/get-started, https://dart.dev/web/debugging. And when I opened the configured chrome devtools, refresh the page. Then the console log the following warnings.

DevTools failed to load SourceMap: Could not load content for http://127.0.0.1:8080/packages/build_web_compilers/src/dev_compiler_stack_trace/stack_trace_mapper.dart.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

I can set breakpoint in dart code in source panel. The debugger stopped at the breakpoint, However the types of variable can't shown.

i am having this issue now out of nowhere

jadamec commented 4 years ago

Same issue here, it would be nice to fix it soon. Thanks!

radverg commented 4 years ago

Same issue, just started using dart and cannot debug properly.

DaljitKhalsa commented 4 years ago

I am also having the same issue on my website too. I am using a plugin name LSCache which i believe is responsible for this. I am having this issue on this site https://bestandcheapbondcleaning.com.au/

If you also see the issue at your end then that mean the issue is not solved. But i will try to fix it from the cache plugin and if it will be possible to update this ticket, i will update it too.

Same issue, Even in the script src="https://unpkg.com/peerjs@1.3.1/dist/peerjs.min.js" but it's loading file from https://unpkg.com/peerjs.min.js.map and getting 404.

Gauravmokashi commented 4 years ago

This worked for me

Go to inspect -> settings gear -> Uncheck 'enable javascript source maps' and 'enable css source map'.

Refresh.

jaydeep-aipl commented 4 years ago

Nice website! I inspected it for errors and don't see any. Did you resolve this problem? I'm getting it in my main.dart file. When I uncheck "enable javascript source maps", refresh -- the error goes away. But on your website, even though that remains checked, I don't see an error. Mine is visible at http://focusonmoney.in. Again, the error I'm getting is with main.dart.

Same problem- none of the workarounds are working. I can see the files and all of the respective folders, but when I click on the file, I get an error.

nshahan commented 2 years ago

I can confirm when running webdev serve some files don't look like they are being served correctly:

@annagrin I labeled this as webdev but I suppose if could be a failure of file copies into the right location during the build, not sure exactly.

Pre1ude0 commented 2 years ago

Sorry for reopening this thread but i still cant fix this even after trying everything. I would appreciate if someone would link a fix. Edit: FIXED THIS: was using betterdiscord and there was a faulty extension that overloaded my pc.

casualPavel commented 2 years ago

Seems to do the trick. Are we missing anything with those two things disabled? Yes and no. Here's an article:

What are Javascript Source Maps?
